Speed:
As you know computer can work very fast. It takes
only few seconds for calculations that we take hours to complete. You will be
surprised to know that computer can perform millions (1,000,000) of
instructions and even more per second. Therefore, we determine the speed of
computer in terms of microsecond (10-6 part of a second) or nanosecond (10 to
the power -9 part of a second). From this you can imagine how fast your
computer performs work.

Accuracy:
The degree of accuracy of computer is very high and
every calculation is performed with the same accuracy. The accuracy level is
determined on the basis of design of computer. The errors in computer are due
to human and inaccurate data.

Diligence: – A
computer is free from tiredness, lack of concentration, fatigue, etc. It can
work for hours without creating any error. If millions of calculations are to
be performed, a computer will perform every calculation with the same accuracy.
Due to this capability it overpowers human being in routine type of work.

Versatility: – It
means the capacity to perform completely different type of work. You may use
your computer to prepare payroll slips. Next moment you may use it for
inventory management or to prepare electric bills.

Power of Remembering: – Computer
has the power of storing any amount of information or data. Any information can
be stored and recalled as long as you require it, for any numbers of years. It
depends entirely upon you how much data you want to store in a computer and
when to lose or retrieve these data.

No IQ: – Computer is a dumb
machine and it cannot do any work without instruction from the user. It
performs the instructions at tremendous speed and with accuracy. It is you to
decide what you want to do and in what sequence. So a computer cannot take its
own decision as you can.

No Feeling: – It
does not have feelings or emotion, taste, knowledge and experience. Thus it
does not get tired even after long hours of work. It does not distinguish
between users.

Storage:
– The Computer has an in-built memory
where it can store a large amount of data. You can also store data in secondary
storage
devices such as floppies, which can be kept outside your computer and can
be carried to other computers.
